I am using iTunes on both a Macbook Pro as well as a Gateway laptop using Windows. I recently noticed when importing about 50 mp3's that only 45 were imported. I started troubleshooting with one of the mp3's that did not import and didn't notice anything peculiar about it. It was in mp3 format, wasn't locked, etc etc.
I've tried importing these 5 tracks numerous ways: Dragging into iTunes, manually importing via iTunes submenu, etc., to no avail.
I recently downloaded a free trial of a audio file converter - and basically converted an mp3 into the same mp3 format. iTunes accepted this file.
My question is: Is there any way to get iTunes to accept these problem files without going through the pain of buying an audio converter and doing the above procedure that I mentioned?
Also, my files are all saved on external hard drives. I've dragged folders of songs into iTunes and I'm estimating that only 80% of them or so actually were imported into iTunes. Is there an easy way of finding and sorting which files were not imported?? Is there another program similar to iTunes that can be used to organize/play music?
I use iTunes to quickly find tracks which I copy to my Apple Macbook Pro's hard drive prior to dragging into Serato (so the external hard drive's speed isn't a limiting factor)
Thank you for your help in advance

sounds like somebody's been downloading badly tagged mp3s! don't worry, i won't tell anyone.
